` v GM IMPROVZElD INCLINBFLANE ELEVATOR.

To all whom it may concern: i i

-Be it `known that I, THOMAS B. Smox'ro'x, of Wilf liamsbnrg, in `t-hecounty of Kings, and State otNeiv York, have invented a new and useful'Improvement in InelinedLvPlane Elevator; and I do hereby declare thatthe following is a full, clear, and exact description thereof,whichwillienable others skilled in the art to make and use the samereference being had to the accompanyin drawings forming part of thisspecitication, in whic .i

Figure 1, Sheet I, is a vertical section of my im-l Figure 2, Sheet I,is a detail cross-section of one of the ways and sliding bars of thesaine. Figure 3, Sheet I, is a detail side view of one of thescroll-wheels. y

Figure 4, SheetfII, is an nnderfside view of my i1n fproved elevator,part of the frame-work being broken away to show the construction.`

Similar letters ofreference indicate corresponding Darts- 4 y f i forits object to improve the construction of my improved elevator patentedNovember 24, 1868, and numbered 84,385, so as to adapt it for use uponthe inclines of railways for carrying cars up and down said inclines;and

It consistsin the construetionand combination of various parts of theapparatus, as hereinafter more fully described.

l i `A represents the frame-work `of theelevatoll, tothe side parts ofwhich the ways B are securely attached. C are bars that slidelongitudinally upon the ways are connected.

The upper and lower edges of the ways B are grooved longitudinally, andthe slidingr bars C are made with hook flanges, which enter the groovesin the ways B, and thus hold the sliding bars 'iu their` places uponsaid ways. y

To each of the ways B is pivoted aseries or row of 13, and with whichthe movable parts of the elevator rollers, D, upon which the spiral`serollot' the scrollwheels E `take hold, so that the elevator-platformmay be'raised or lowered by revolving the scroll-wheels E in one or theother direct-ion. p

The scroll-wheels E revolve upon axles, attached in an inclined positionto the sliding bars G, `so that the upper sides of the saidscroll-wheels E may beinclined inward, as shown in fig. 4, toenable thescroll of said wheels to work properly upon the rollers| D of the `Inthe rim of -tlle scroll-wheels EI are formed teeth, into which mesh. theteeth of the gear-wheels F, attachedA to the shaft G, so at the saidgear-wheels F maybe revolved to operate he scroll-wheels E by revolvingsaid shaft G.

the purpose set forth.

To the shaft G are also attached iianged wheels H, the treads oi' whichroll upon the rails I of the track,

which rails' I may be attached to ties laid upon the ground or attachedto the frame-work A of the elevator, as circumstances may require.

J is another set of flanged wheels, rolling upon the track I andattached to the axle K, which is connected `with the sliding bars C.

One or more of the flanged wheels -H J have teeth Aformed upon the edgesoftheir flanges', which mesh into the teeth of racks formed in orconnected vwith the rails I, as shown in Bg. 1.

L is the platform, which is connectedwith and supf ported from the axlesGr K by a frame-work, M, which is so constructed as to support the-saidplatform L `in a horizontal position while passing up and down theincline.

` vN `is the endless rope or chain, by means of which the apparatus `israised and lowered.

The endless rope or chain N passes around the pulley or wheel O,attached to one or the other of the axles G K, making one or more turnsabout said pulley.

The rope or chain N passes around the pulleys I and Q, attached to theshafts R and S, secured, respectively, t-o suitable supports at theupper and lower ends of the incline.

The elevator may be operated by power applied to one or the other ot'the shafts It S, as maybe convenient.

Upon one or more of the wheels E H 'J are formed anges, upon which theshoes of the brakes T may operate. i

The brakes T may be applied by means of levers V, passing up at thesides or ends or through slotsin the platform L, so that they maybeconvenientlyoperated by the attendanty or attendants standing upon saidplatform. f

- The brake or brakes T U should be powerful enough to stop and hold theapparatus `and its load at any point of the incline, should anything getout o f order or break,'or should it be necessary from any other causeto hold the apparatus stationary.

Having thus described my invention,

I claim as new and desire to secure by Letters` 1. The series or rows ofrollers D, in combination with `the ways B and sliding bars G with whichthe movable parts of the elevator are connected, substantially as hereinshown and described, and for the purpose set forth.

2. The combination of the hooked ianges of the sliding bars O with thegrooved sides of the ways B, substantially as herein shown anddescribed, and for 3. The combination of the flanged Wheels and tracks5. In combination with the rails I, gear-wheels F, H J with thescroll-wheels E, sliding bars C,m1d ways rollers D, and ways B, thewheels E H J and brakes B, substantially :is herein shown and described,and T U, as and for the purpose set forth. for the purpose set forth.The above specification of my invention signed by 4.
